The volumetric performance of machine tools is limited by the remaining relative deviation between desired and real tool tip position. Being able to predict this at any given functional point enables methods for compensation or counteraction hence reduce errors in manufacturing uncertainties on-machine measurement tasks. Time-efficient identification quanitification different contributions resulting play a key role strategy. authors pursue development an optical sensor system step diagonal methods, which can be integrated into working volume due its compact size, enabling fast measurements axes’ motion error including roll, pitch yaw squareness without significantly interrupting process. use frequency-modulating interferometer photosensitive arrays combination with Gaussian laser beam allow comparable accuracy, lower cost smaller dimensions compared state-of-the-art measuring appliances offline calibration. For validation method virtual setup raytracing simulation used investigation systematic like hardware misalignment.
